Police say that new scientific evidence shows that David Morris was correctly convicted
SOUTH WALES POLICE say that an independent investigative assessment into the Clydach murders in 1999 have shown that there is a scientific link between David Morris and a sock, widely accepted as being used by the offender during the killings.
David Morris was found guilty of murdering an entire family of four including two young girls.
But potential new witnesses, along with the views of experts, had given campaigners calling for his release fresh hope.
However Morris, 59, died in prison in August.
He spent 22 years in jail for killing Mandy Power, 34, her daughters Katie, 10, and Emily, aged eight, and her 80-year-old mother Doris Dawson.
A bid to again take his case to the Court of Appeal was rejected in 2018 by the Criminal Cases Review Commission.
In July the Crown Prosecution Service said no information had been provided by the potential new witnesses to undermine the conviction.
The review, which was being overseen by Devon and Cornwall Police, was then expected to move on to look at forensic issues also challenged in a recent BBC television documentary about the killings.
Police say that the scientific examination of the sock has identified the presence of a mixed *Y-STR profile using technology which would not have been available to the original investigation team over 20 years ago.
While the presence of a link to Morris (or a male relative of his paternal lineage) and the mixed Y-STR profile has been identified, the science cannot determine how or when this profile was transferred onto the exhibit, but the conclusion of scientists is that it is “more likely” that Morris contributed to the DNA profile found on two different areas of the blood-stained sock than if he did not contribute DNA to them.
Following the tragic events in Kelvin Road, Clydach in June 1999, South Wales Police carried out an extensive investigation into the murders and the scale of the investigation was the largest and most complex ever undertaken by a Welsh police force.
In 2002, David Morris was convicted of the murders by a unanimous verdict at Swansea Crown Court. His conviction was overturned on appeal due to a conflict of interest by a defence solicitor. A retrial was held at Newport Crown Court in 2006 and Morris was convicted again. He was sentenced to life imprisonment.
The matter has been considered by the Criminal Cases Review Commission as recently as 2018. Following a thorough review of the case material they decided not to refer it to the Court of Appeal as no new evidence had been identified.
In November 2020, legal representatives of Morris contacted South Wales Police requesting the release of various exhibits from the investigation.
This request was the subject of careful consideration and the force decided on a course of action which involved the appointment of an independent senior investigating officer and an independent forensic laboratory to oversee a forensic review of the case material.
This work – carried out under the banner of Operation Dolomite – has been led by experienced detectives Steve Carey and Ian Ringrose, supported by police forensic expert David Lloyd, all of whom are from Devon & Cornwall Police. An independent forensic science laboratory, Cellmark Forensic Services, was commissioned to carry out forensic work.
Following the death of David Morris on 20th August 2021, permission was given by his family to obtain a blood sample to allow forensic examinations to take place.
Assistant Chief Constable David Thorne, of South Wales Police, said: “The decision to carry out an investigative assessment did not constitute a reopening or reinvestigation of the murders, nor did it demonstrate any lack of confidence in the conviction of Morris and the subsequent case reviews. Morris was convicted unanimously by a jury on the strength of the prosecution case and independent reviews by the Criminal Cases Review Commission have never identified any evidence which would determine the conviction to be unsafe.
“However, the advancement of forensic technology has provided the opportunity for evidence-based answers to some of the questions which have been raised about forensic issues in this case, along with other matters raised by the BBC Wales documentary ‘Beyond Reasonable Doubt’. The appointment of Steve Carey and his team has ensured the review has been conducted with a layer of independence.”
The outcome of the investigative assessment has been communicated to the victims’ families, the family and legal representatives of Morris and others affected by this case.
Mr Carey said: “My team has carefully examined the issues raised and subject to the terms of reference for Operation Dolomite.
“In the opinion of the forensic scientist regarding these results – which were obtained from samples extracted from two separate areas of the sock at the time of the original forensic examination – it is more likely that David Morris (or a close paternal-line male relative of his) contributed DNA to them than if he did not.
“In relation to one sample, the lead forensic scientist has stated to me that in his opinion the low-level and incomplete mixed Y-STR result is as would be expected if Morris had contributed DNA to it. For another person to have contributed to it, the components must match by chance.
“The scientist would have a very low expectation of selecting a male individual at random from the Western European population having components in their Y-STR profile being represented to the same extent as those in the Y-STR profile of Morris.
“To test this, an evaluative tool developed by Cellmark Forensic Services showed that from a dataset of 9,357 Western European males, no-one is represented to the same extent as the component in the Y-STR profile of Morris.
“It should be noted that the results do not allow the scientist to interpret how the DNA got onto the sock and therefore whether this was through directly touching the item or indirect transfer but the identification of this link has been possible due to the development of technology which would not have been available to the original investigation team.
“This is significant as the sock was recovered from the murder scene and it was widely accepted that it was used by the killer.
“The outcome of the forensic assessment and completion of further actions have not established any information that undermines the conviction of Morris. In my view, as the independent senior investigating officer, the new findings from the samples taken from the sock support the existing evidence that originally convicted him.”
Operation Dolomite also investigated accounts provided by two witnesses who featured in the BBC documentary. They were interviewed by officers and several enquiries were conducted to try and corroborate and support their accounts. All this evidence was shared with the Crown Prosecution Service. None of the information provided by the witnesses undermines the conviction of Morris.
ACC Thorne added: “Notwithstanding the fact that Morris has been convicted based on overwhelming evidence against him, South Wales Police has shown a commitment to providing evidence-based answers to the issues which have been raised about this case over many years.
“This commitment has now resulted in a forensic link between the convicted killer David Morris and an item of great significance which was recovered from the murder scene. South Wales Police commissioned the review in the hope that we could in some way provide closure for those most affected by the murders. In particular, those who lost three generations of the same family and have had to revisit those painful memories time and time again over the last two decades.
“The findings from Operation Dolomite will be shared with the Criminal Cases Review Commission to complete the due process and demonstrate transparency. However, in the knowledge of the conclusions drawn from this review, South Wales Police would like to show respect to the family and those affected by these terrible crimes by finalising this case.
“Our thoughts as ever remain with the family of Mandy Power, her children Katie, aged 10, and Emily, eight, and her 80-year-old mother Doris, who still experience such painful memories even to this day.”
Following the refusal by the CPS to look at new evidence before David Morris died, Janiene Morris, one of David Morris’s two daughters, said: “This is another massive blow to dad’s case and as a family we just don’t understand it.”
She said at the time that the evidence of a taxi driver who had sighted unidentified people near the murder scene had been discounted. In all, she said there were three witnesses that had placed others near the murder scene on the night of the killings.
“We’ve never met them and don’t want to because we want to do things properly. These witnesses have was not involved with anyone in the case and have absolutely no reason to lie. I cannot express how angry and frustrated we are right now. It is so frustrating, but we’re not going to take it lying down”.
Speaking in July, Janiene said: “He is up and down. He has good days and and bad days. Sometimes he is just exhausted with everything that is going on. We are looking forward to seeing him.”
